AT&T MVNO with international plans
Type: MVNO · Network: AT&T · Official site
Our take on H2O Wireless
What’s good
- Third-party AT&T MVNO — same network as Cricket, often at lower retail prices
- Strong international calling story: bundled minutes to 60+ countries on most plans
- Available at small retail (corner stores, ethnic markets) for cash refills — useful for users avoiding linked bank accounts
- No contract; bring-your-own-phone friendly
- Eligible MVNOs route through Cricket-tier priority on AT&T (post-2024 changes)
What’s not
- Third-party-MVNO deprioritization on AT&T — gets queued behind AT&T postpaid AND Cricket during congestion
- Customer support is chat/web only and notoriously unhelpful for billing disputes
- Hotspot allotments are minimal vs Visible / US Mobile
- AT&T mid-band 5G+ access is gated — H2O typically only gets low-band 5G
Best for: Users who specifically need AT&T-network coverage with international calling baked in, and who don’t mind chat-only support.
Not for: Users in dense urban congestion areas — the deprioritization story makes AT&T-direct (postpaid or Cricket) the better pick.

Frequently asked questions
- What network does H2O Wireless use?
H2O Wireless is an MVNO that runs on the AT&T network. Coverage is identical to AT&T postpaid in any given location, since both ride the same towers and spectrum. Speeds during congestion may be slightly lower because MVNO traffic is deprioritized vs the underlying carrier's postpaid customers.
- Is H2O Wireless an MVNO or MNO?
H2O Wireless is an MVNO — a Mobile Virtual Network Operator. They lease wholesale capacity from AT&T and resell it under their own brand at typically lower prices.
- What is the cheapest H2O Wireless plan?
The cheapest H2O Wireless plan we have on file is 5GB at $30.00/month. See the plans table above for the full list.
- Where can I check H2O Wireless coverage?
H2O Wireless rides the AT&T network, so its coverage is the same as AT&T's. We have a county-level coverage map at /coverage/h2o, derived from public FCC Broadband Data Collection data. Enter your ZIP to see strong/fair/poor/none classification at your specific address.
- How do I switch to H2O Wireless from another carrier?
Sign up at https://www.h2owirelessnow.com, choose "transfer my existing number," and provide your current carrier's account number, port-out PIN, and billing ZIP code. Most ports complete in 15 minutes to 4 hours. Never cancel your old service before the port completes — it usually closes automatically. See our switching guide for the full walkthrough.
- Can I bring my own phone to H2O Wireless?
Yes — H2O Wireless supports BYOD. Your phone needs to be unlocked (carrier-locked phones must be unlocked first by the original carrier) and band-compatible with the underlying network. Activation is via eSIM or physical SIM depending on the device and carrier.
- Does H2O Wireless support 5G?
Yes. H2O Wireless supports 5G via the underlying AT&T network — sub-6 GHz (low-band + mid-band/C-band) on most plans. mmWave 5G availability depends on the specific plan tier and your phone's hardware. Speeds in the 200–700 Mbps range are typical on mid-band 5G in covered areas.
